Disk-Usage
rdiff-backup 需要太多空間來從以前的備份失敗中恢復？
我在這個文件系統上有很多可用空間（和 inode），但
rdiff-backup顯然空間不足。因此我的備份目前無法正常工作:-(。為什麼？（我想知道將來我應該為此保留多少空間！）
我的 rdiff-backup 是 version
1.2.8-7。我的作業系統是 Debian 9 “stretch”。# df -h /d/backup Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_brick-lv_backup 139G 95G 38G 72% /d/backup # df -i /d/backup Filesystem Inodes IUsed IFree IUse% Mounted on /dev/mapper/vg_brick-lv_backup 9240576 413341 8827235 5% /d/backup # df -h Filesystem Size Used Avail Use% Mounted on udev 244M 0 244M 0% /dev tmpfs 51M 1.9M 49M 4% /run /dev/sda7 15G 4.1G 9.8G 30% / tmpfs 251M 0 251M 0% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 251M 0 251M 0% /sys/fs/cgroup /dev/ubi0_0 462M 225M 233M 50% /d/ubi tmpfs 251M 4.0K 251M 1% /tmp /dev/mapper/vg_brick-lv_attic 44G 21G 21G 50% /d/attic /dev/mapper/vg_brick-lv_backup 139G 95G 38G 72% /d/backup /dev/sda6 2.0G 81M 1.8G 5% /boot /dev/mapper/vg_brick-lv_home 134G 91G 37G 71% /home /dev/sda10 9.8G 2.9G 6.9G 30% /d/xfer tmpfs 51M 0 51M 0% /run/user/1003 root@brick:/d/backup/jenkins-desktop# du -sh mike 5.7G mike root@brick:/d/backup/jenkins-desktop# du -sh ../jenkins-desktop.rdiff/mike 8.2G ../jenkins-desktop.rdiff/mike root@brick:/d/backup/jenkins-desktop# rdiff-backup mike ../jenkins-desktop.rdiff/mike Previous backup seems to have failed, regressing destination now.

您需要禁用 tmpfs on
/tmp，或者配置rdiff-backup為使用其他有足夠空間的臨時目錄。可能/var/tmp。tmpfs 251M 4.0K 251M 1% /tmp還原或回歸時，rdiff-backup 需要預設臨時目錄中的可用空間。在 unix 系統下，這通常是 /tmp 目錄。rdiff-backup 使用的臨時目錄可以使用 1.1.13 和更新版本中可用的 –tempdir 和 –remote-tempdir 選項設置。有關預設臨時目錄的更多資訊，請參閱 Python tempfile 文件中的 tempfile.tempdir 條目。所需的可用空間量可能會有所不同，但通常大約是要恢復的最大文件的大小。
